K8200 / 3drag GT2 belt extruder

thingiverse

Transform your extruder to belt drive for less noise and prolonged motor life with this 80-tooth GT2 pulley. Includes an openSCAD parametric CAD file that can be customized by altering the number of teeth. The design is based on a popular library available at Thingiverse. Be cautious when using flexible materials like nylon, as it may not perform well. Print settings include raftless and support-free prints with 0.3mm layer resolution for best tooth detail. For optimum torque, consider printing an 82-tooth version or use a 20-tooth pulley on the motor side. Note that belt direction changes compared to gears, so you'll need to rebuild and reprogram your machine accordingly. Check the code line in configuration.h for related settings and adjust steps/mm from 600 to 682 for the new ratio of 16:80.
